If you're working on a Mac, you should first install Apple's freely available 
OSX developer tools, known as "Xcode". That will install lots of other tools 
and libraries, including zlib, so you won't have to build it. You'll also have 
the OSX C compiler, which works well for building netCDF on a Mac:

  
https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man3/zlib.3.html

I've never seen the error message about -Werror before from configure, so don't 
know what's causing it, but having Xcode installed is needed if you're going to 
build the netCDF-C library from source.

If installing from source proves too problematic, you can instead get prebuilt 
netCDF libraries for OSX from homebrew or MacPorts. Since you may need a 
Fortran compiler to use netCDF with WRF, that's also automatically installed by 
using homebrew or MacPorts to install their "netcdf-fortran" package.
